SCRAPER.

Patented Sept. 24, 1907.

Application filed November 28, 1906. $erial No. 345,520,

To all whom it may concern:

Be it known that I, HENRY JAMES BICKLE, of the town of Gladstone, in the Province of Manitoba, Canada, inventor, have invented certain new and useful Improvements in Scrapers, of which the following is the specification.

My invention relates to scrapers, more especially wheeled scrapers, and the objects of the invention are to provide, firstly, a scraper with a swing lift pan completely under the control of a single operator, and in which the draft animals supply all the necessary energy for dumping, secondly, to provide a scraper which allows that the draft animals may remain continuously on the road bed while operating, thirdly, to provide a scraper which will practically eliminate all unnecessary heavy neck work or undue strain on the draft animals, and lastly to provide a novel locking device for retaining the pan in several operative positions, the parts being arranged and constructed as hereinafter more particularly described.

Figure l is a perspective view of my complete invention; the pan locked in the upper position. Fig. 2 is a side elevation of the scraper; the pan locked in one of the lower positions. Fig. 3 is a side elevation of the scraper; the pan in a dumping position, being freed from the locking bar. Fig. 4 is a plan view of the scraper, the pan being unlocked previous to dumping. Fig. 5 is a side elevation of a second embodiment of my invention. Fig. (5 is an enlarged, detailed, perspective view, showing the wheel spindles, the pan suspending bar, and a broken portion of the frame or side bars, to which the draw bar is secured. Fig. 7 is an enlarged, detailed, perspective view of a portion of the draw bar and the lock bar. Fig. 8 is an enlarged, detailed, perspective view of the means employed for securing the tongue to the draw bar. Fig. 9 is a side view showing the bail bar on the scoop.

Heretofore it has been the practice when dumping the pan, that several men lift on a pair of handles, secured, one at each side of the pan, and consequently much extra labor was involved. I consider it one of the prime features of my invention, that the pan is pivotally suspended by a bar, fastened rearwardly andbolow the center to the sides, and not as ordinarily employed by a bar secured rigidly to the pan. Suspension in this manner gives me an added moment, and the swing lift, which is used to advantage.

A A are the carriage wheels and B the pan which is of the ordinary form.

C is the bar suspending the pan and has its extending ends O C bent substantially at right angles to the body and flattened.

O are the stub axles for the carriage wheels secured one at each side, to the portions O C and upwardly towards the angle in the bar. It will be understood that the axles are normally horizontal.

D D are bolts passing through the lower end of the portions O C and through the side faces of the scraper, and are retained in position by nuts in the ordinary manner. As pointed out above, the bolts pass through the pan rearwardly and below the center of the sides.

E E are side bars which form practically the framework of the scraper. They are pivoted at'their front end at the base of the axles O and pass rearwardly, being bent inwardly around the back of the scraper, and then rearwardly, forming aside plate, to which is secured the front end of the push or drag bar E, by bolts E F are braces, one on each side, secured across the angle of the bar E.

The drag or push bar E is hollow, and has a slidable rod or locking bar F passing centrally therein. The drag bar has a portion G cut away from its upper side, as clearly shown in Fig. 7, and the adjoining end of the drag bar is open. The lock bar also has a portion cut away, the cut enlarging from the top inwardly, forming a recess with acute angled ends G H is a flat bar of a V-shape, having its ends flanged, and secured to the rear of the pan by bolts H The angle of the V-shape is squared at H in order that it may pass more readily into the incision G in the looking bar. The thickness of the bar H is such, that when in the incision G its upper face is below the surface of the level of the locking bar. It is to be understood that the width of the bar H is such that it can easily clear from the opening in the bar F 1 I are braces passing obliquely downwardly from the upper edge of the rear of the pan, and attached to the V-shaped bar on either side of its center.

The rear end I of the drag bar E is flattened somewhat, in order to form a bearing surface for a circle and several other attachments, and has an opening I cut longitudinally and centrally therein.

J is a plate secured to the side face of the drag bar, and J is a toothed quadrant secured to the other side of the bar and directly opposite the plate J.

K is a shaft extending across the end of the drag bar above the opening I and bearing at either side within the plate J and the quadrant J respectively.

K is an arm secured rigidly to the shaft and passing downwardly therefrom, its lower end being connected by means of a rod K to the locking bar F.

L is a handle or lever attached to the end of the shaft K and is provided with a hand latch L operating detents cooperating with the notches in the arch in order to secure said lever in any desired position on the arch or quadrant. The quadrant may be completely toothed, but it is only necessary to have a sufficient number of teeth to be able to hold the lever in three positions, for

convenience in operating it is preferable to have the lever with the lower end turned somewhat out of alinement with th ebody; such allowing that the .lever is;

never thrown farther forward than the vertical position.

M is a circle with its edges flanged or tiuned outwardly, the said circle having wings M securing it to the end of the draw bar.

M is anannular ring enveloping the body of the cir cle M and retained thereon by the flanges, and has a rear extension M to which is secured the seat spring N, in turn supporting the seat N N is a portion extending forwardly fromthe ring and to which is secured a tongue by means of a side plate directly under the control of a hand wheel P readily operated from the seat in all positions.

The three-required positions ofthe lever Lvare the vertical, the horizontal, and one practically midway between. tively in Figs. 1, 2, & 3, and the corresponding positions of the pan for these positions isalso shown.

Assume the locking bar F to be in the position, as shown in Fig. 7, relative to the drag bar, such being when the lever L is in the intermediate position, between thevertical and-horizontal. In this case .the portion H of the bar H is free to drop into or clear from the incision G Assuming further that the pan is,-as shown in Fig. 4, that is with the portion resting in the incision. Upon throwing the lever to the horizontal, (see Fig, 2 the pan is swung downwardly, till the tip comes to the ground level. This is caused by the edge of the barI-I coming in contact with the slant face G of the lock bar, and being forcedforwardly by the forward movement, due to the lever. I When thelocking bar is in such forward position the portion H of the bar H is retained or locked within the incision G by means of the overhanging lip Q of the drag bar, and consequently it is impossible for the pan to move from its -position.- Upon bringing the lever L to the vertical position see Fig. 1), the bar H is carried rearwardly by the notch in the locking bar, and the pan is lifted clear of the ground level and retained in its position by a lock similar to that above described; the-portion H being held in position' by the other slant side G of the lock bar and the overhanging, portion Q of the drag bar. it v I l 1 I From the above description it will be seen that the pan can be locked by theoperator int'wo positions and released at will, the whole being under the control of the lever L, and to better understand the features of the machine its operation in use is hereinunder de scribed. I V 4 I l A team is attached by the usual doubletree and neck yoke to the tongue 0, and the operator takes his place on the seat. When it is required to fill the pan the team is turned around-facing the pan, the tongue being then ina position directly-above the drag-bar. The operator throws the lever downwardly to the horizontal These various positions are shownrespec position, which throws the pan with the tip to the ground, and locks it there (see Fig. 2). As ordinarily employed: in scrapers when filled, I snatch team is used, and it is attached to a bail bar R, which is pivoted to the pan by pins lt on thereof. As shown the bar is bowed and passes across the front of the pan. R is an arm attached to the bail bar and R a spring w ch passes from the arm to a pin on the pan. R is sang to which a rope from the whifHe-tree of the snatch team is attached. The position of the front portion of the bail is directly below the drag bar. In this way, it will be noted, that it is impossible for the pan to fly up, or turn over, as it is locked in position. After the pan has been filled, the snatch team is taken off, the lever is thrown to the vertical position and the pan raised clearof the ground and locked in that position. When it is required to dump, the lever is thrown to the central or midway position, the top of the pan touches the ground and the portion H of the bar H is allowed to freeitself from the incision G The team is driven forward, and the slight drag of the tip of the pan on the ground is sufficient to upset or dump the pan, it coming into the position shown in Fig. 3. As soon as the earth or such like is all clear from the pan, the team is turned aroundfacing in the opposite direction, and the pan drops again with the portion H within the incision G The lever is then thrown to the upper or vertical position and the pan is locked clear of the ground. It will be understood that although I have spoken of the tip of the pan touching the ground with the lever in the horizontal and the midway positions, yet with the lever in the horizontal position, the wheels can be lifted clear of the ground, thus allowing the pan to scrape. Throughout all operations the swivel wheel is directed by the operator from the seat. It will be noted that there are no extending handles to be used in dumping, and by the simple swing lift the necessity of having extra men to aid in dumping is avoided.

In using the scraper to fill excavations, etc., a great deal of time is saved, by being able to dump directly over the side of the excavation. The team can be driven so that the scraper comes to the edge andis dumped, the team remaining continuously on the road bed. In building through sloughs it is unnecessary for the team to go into the water and get their feet wet.

A second embodiment of my invention is shown in Fig. 5, in which the scraper can be described as a pull scraper, distinguishingit from the one hereinbefore described, which could be called a push and pull scraper. In this case the pan is supported in exactly the same manner as in the other, but the drag bar is shortened, and just of sufficient length to allow for operation of the locking bar. 5 Referring to the drawing, S is the drag bar and S the locking bar, operated by the lever L, working in the quadrantl as in the before mentioned case. The lever operates the locking and locks the pan exactly as before. The swivel wheel P has not a hand wheel to operate it and it simply turns of its own accord. The bars E extend forwardly above the pan in practically the same manner as they pass to the rear, and have secured at" the front a tongue 0, which is pivoted by means of a pin 0 to the forward ends of the bars. 0 are braces like those F, passing across and reinforcing the bars. In using this form of scraper it will be found a great deal more convenient than that heretofore employed, on account of having the pan controlled by a single oper ator and embodying as it does the swing lift pan, doing away with a great deal of unnecessary labor.

Referring to Fig. 2 it will be noticed that the pan is dotted in a reversed or overturned position, with its I edges lying on the side bars or framework E, and the and means whereby the pan may be locked in an upper or lower position, as and for the purpose specified.
